Before the electroencephalogram experiment process, the scalp needs to be subjected to conductive paste smearing operation in advance so as to be connected with an electroencephalogram tester, and the monitoring of electroencephalogram is realized.

However, the existing device for injecting the brain cap conductive paste has the following problems:

because the existing conductive paste has the defect of poor fluidity, the conductive paste is easy to be smeared unevenly when being smeared, the time is wasted, and because the head part has hair, the wetting speed of the conductive paste is promoted to be slow, the conductive paste is easy to flow and diffuse under the action of thrust, and the problems of short circuit conduction and the like between adjacent electrodes are caused.

We have therefore proposed a device for the rapid injection of electroconducting paste for brain caps, in order to solve the problems set out above.

and one end of the injector piston is movably arranged in the conductive paste injector.

Preferably, the lateral part of the brain electricity cap fixing ring is evenly installed with the lug that can strengthen frictional force, and 2 are installed in the fixed ring of brain electricity cap in the outside of electrode fixer for when utilizing 2 brain electricity cap fixing rings to install the device on general brain electricity cap, the lug can strengthen frictional force each other, improves the installation fastness.

Preferably, rubber bowl and tongue piece are the rubber material setting, and the cross section semicircle ring-type of tongue piece to the tongue piece is about the center of rubber bowl is the angular distribution such as centre of a circle for wear the experimenter head with the brain electricity cap after, the tongue piece can be to spreading all around and pluck open the hair, thereby can expose the scalp.

Preferably, the conductive paste injector and the electrode fixer are made of hard plastics, and are in interference fit with each other, so that the cost can be reduced, plugging and unplugging are facilitated, and the electrode fixer is simple and convenient.

Preferably, the outer side of one end of the syringe piston is attached to the inner wall of the conductive paste syringe, and the syringe piston and the conductive paste syringe form a concave-convex fit, so that when the syringe piston is pushed inside the conductive paste syringe, the conductive paste can be injected.

Compared with the prior art, the invention has the beneficial effects that: the device for rapidly injecting the brain electric cap conductive paste;

1. the rubber bowl is attached to the scalp, so that the conductive paste can not flow out and diffuse, and the problem of conduction short circuit between the electrode bodies is avoided;

2. when the rubber tongue piece is worn and extruded downwards integrally, the rubber tongue piece can be scattered to the periphery, and the hair in the bowl can be pulled away to the periphery in the process, so that the contact between the conductive paste and the scalp and the infiltration of the scalp are facilitated, and the time for infiltrating the conductive paste and reducing the impedance is greatly shortened;

3. after the rubber bowl is filled with the conductive paste, the contact surface of the conductive paste and the scalp is a bowl mouth cross section, which is greatly increased compared with the contact surface of the traditional cylindrical fixer, and is very favorable for shortening the time of wetting the conductive paste and reducing the impedance;

4. compared with the prior art, the caliber of the injector is greatly increased, which is not only beneficial to quickly absorbing the conductive paste, but also beneficial to quickly injecting (the paste body has poor fluidity), and in addition, the scale is printed on the outer wall of the injector, which is convenient for controlling the dosage.
